CAN-SOLDERING MACHINE.

SPECIFICATION forming part of Letters Patent No. 295,662, dated March25, 1884.

Application filed January 15, 1884. (No model.)

.useful Improvements in (Jan-Soldering Machines, of which the followingis a specification, reference being had therein to the accompanyingdrawings.

My invention relates to improvements in can-soldering machines in whichfloats or end seams of-round cans are soldered; and the objects of myimprovements are, first, to either solder one or both the end seams atthe same time; second, to either solder the can from the cap or solderin the head of the can when filled with the goods; fourth, to providemeans that will protect the side seam from being unsoldered when theheads are being soldered in; fifth, to support the mechanism on acentral vertical shaft and from a suspended hanger.

. I attain these objects by the following mechanism, illust-rated in theaccompanying drawings, in which V Figure 1 is aside view of the entiremachine, part of which is in section; Fig. 2, atop view of the hangerand gear-wheels; Figs. 3 to 8,

, enlarged detail views of the mechanism that imparts the intermittentmotion to the rotary table; Figs. 9 and 10, details of the arm andsegment shaped piece that raise the canclamping disks; Fig. 11, a topview of the upper plate of the rotary table; Figs. 12 to 20, detailviews of can-holders; Fig. 21, side view of the machine when adjustedfor capping the filled cans; Figs. 22 and 23, detail views of capholdingdevice, and Figs. 24: and 25 views of the cans.

Similar letters refer to similar parts throughout the different views.

The hanger A is suspended from above and provided with a yoke, throughwhich the lineshaft B passes. On the latter is a pinion, a,

clutched thereto by means of the sliding clutch b, provided with thelever 12, by which the machine is operated.

Through the perpendicular sleeve A of the hanger A passes the verticalshaft 0, the lower end resting in the bearing f on the floor.

. To the shaft 0 are attachedthe gear-wheel a,

which engages with the pinion a on the lineshaft B; the crank c, whichvibrates the pendulum D; the external master gear-wheel, E, whichrotates the can-holder (I when 'in an inclined position; the internalmaster gearwheel, F, which rotates the can holder d when perpendicular;the cam e, which operates the solder-valve mechanism, and the rotarytable G is supported and rotates freely thereon.

The table G consists of an upper and lower plate, 9 and 9, connectedrigidly together by means of the sleeve h. Attached. to the periphery ofthe lower plate, 9, are yokes t, in which the hubs 13 are swiveled, andwhich are held or adjusted to the desired angle to engage the pinion kwith either of, the masterwheels E or Fby means of the segment-shapedslot Z onone arm of. the yoke i, and a clampingscrew, f, which passesthrough the slot Z and into the hub 03. In the hub t" runs the spindlei, to which is attached the can-holder d and the pinion 7a The upperplate, g, is provided with an upward cylindrical projection, 9 in whichare notches g ratchet-teeth u, and arms m, projecting therefro1n,whichhave upper and lower bearings, m and m, through which the spindle ipasses.

To the spindle i is attached a clamping plate or disk, n, which holdsthecan Hfirmly in the holder d by means of the spring a, i which bears downon a flanged collar, a, attached to the spindle tfby means of asetscrew, it", which allows the collar n to be adjusted to suit theheights of the different cans. The spindle t and its attachment arelifted by the flanges n of the collar 11?, which comes in contact withthe segmentshaped piece 0 on the outer end of the arm 0 as the table-Grotates, the latter stopping with the can-holder d opposite the ,centerof the arm 0, thereby holding the clamp or disk 02 up, allowing theoperator to conveniently place or remove the cans; The intermittentmovement is imparted to the table G by means of the crank g on the shaft0, provided with a roller, 0, which comes in contact with the adjustablelugs or projections 19 and p onthe pendulum D, alternately. The pendulumD is pivoted to the downward-projecting rod g at one end, and providedat the opposite end with the hollow boss 1', containing therein aspring, and the pin 1", which engages with the ratchet teeth a on theplate 9. As the crank c rotates, the roller 0 comes in contact with thelug 0, thereby moving the pendulum D to one side, which then remainsstationary until the crank 0 makes part of its circuit, or until theroller 0 comes in contact with the .lug p, which will move the pendulumD'in the opposite direction to which it was first moved. The pin a" inthe meantime engaging with a ratchet-tooth, u, on the plate 9, the tableG is rotated one-twelfth of its circumference, and then remainsstationary until the roller 0 again comes in contact with the lug 10. Bythe aforesaid mechanism the table G is rapidly moved after the can issoldered, thereby freeing the can from the heat quickly, at the sametime starting and stopping the table gradually. The table G is heldrigid while the cans are being soldered, placed, or removed by the pin tin the sleeve t, engaging in the notches g on the plate 9, and relievedtherefrom by the lever m, connected to the pin it at one end, and at theopposite end pivoted to the rod q, the lever being lifted by theupward-projecting incline s on the crank 0, coming in contact with thedownward-projecting incline s on the lever m at each rotation of theshaft 0.

To the downward-projecting rod q at the lower end is attachedaprojecting arm, 9, provided with a brake-shoe, g, which bears down onthe cylindrical projection 011 the plateg, which prevents the table Gfrom jumping forward when in motion, the whole being suspended from thecross-arm A, which is attached to the hanger A by means of the setscrews6 e.

The can-holders consist of cylindrical rings (Z, arms (2, and notchedplates d. The plates at are placed on the arms d, and are held to their.places by the notches Z, fitting over the upward projections d of arms(1, to prevent the scorching or discoloring of the can ends and thecap-crease. The outer ends of the arms (1 have upward projections (1 towhich is attached the ring (1, allowing the end of the can which restson the arms d to project below the ring (1 sufficient only to melt thesolder therein, thereby protecting the upper part of the can from theheat and effectually preventing the melting or unsoldering of the sideseam. The holders d are changed to suit the different-sized cans bymeans of auxiliary rings is, the inner diameter of the same suiting thesize of the cans to be soldered, while the outer diameter neatly fits inthe ring d. The projecting shoulder on ring It prevents the same fromentering the ring (1 too far. To

each set of auxiliary rings are corresponding bottom plates, d. By thisconvenient arrangement any sized can smaller than the cylindrical ring dcan be soldered, and in case of larger cans special holders areprovided.

The arm I is attached to the cross-arm A by the rod q, provided with aclamping-nut, and has an inward and outward adjustment by means of avertical slot, 0, through which the rod q passes. To the downwardprojection of the arm I is attached a receptacle, L, containing moltensolder, which is ejected on the ends of the cans by means of a valveformed by the rod 1, (see Fig. 21,) which has a cone-shaped end restingin a counter cone in the nipple 2, which forms the seat of the valve,and is operated by means of the bell-crank 3, reciprocating rod 4, came, and draw-spring 6. 1

The machine is operated by one boy, who stands opposite the disk-liftingarm 0, placing and removing the cans, which are soldered in thefollowing manner: When soldering both ends of the can without removingthe same from the machine, the can is constructed as shown in Fig. 24,one end having the flange projecting over the can-body, and the otherend placed insidethe same. Before or while placing the cans on themachine, a segment of wire-solder is placed in the can on the end whichhas the flange projecting over the can-body, the same end being placedin the ring (I. As the cans are carried around by the table G, they comein contact with the flame from the hydrocarbon-burners R, (which areplaced opposite to where the can-holders stop, the number of burnersdepending on the size of the cans and the speed at which the machine isrun-ordinarily about four,) which fuses the solder placed in the can,and which is distributed around the seam by the rotation of the same.The opposite end of the can having the end placed inside the body, (seeFig. 24,) forms a V-shaped groove, in which the molten solder is ejectedfrom the receptacle L by means of the cam e and the interveningmechanism, the heat being applied to the cans from burners placed asthose above stated before and while the molten solder is ejected.

thereon.

Either of the aforesaid methods may be used independent of the other,one end of the can being soldered in at a time, the moltensolder devicebeing used if both end seams of the cans are to be soldered from theoutside,the cans being constructed with both ends placed inside. (SeeFig. 26.) To solder both ends from the inside, the arm I and itsattachments are dispensed with or removed, the can being soldered by theformer method, as above stated, when using the segment of wire-solder,the can being constructed as shown in Fig. 25.

WVhen capping or soldering in the heads of filled cans, the machine isadjusted as shown in Fig. 21, with the can-holder d placedperpendicular, and the arms m on plate 9 removed and substituted by thearms 3 provided with the hollow hubs y, springs as, and pin 00, whichholds the head or cap down in its place, the pin azhaving a cone-shapedend which fits the vent-hole of the cap, and which contains anescape-port, 0 to allow the vapor to escape from the filled cans whenheated,

the soldering being done by ejecting molten solder in the cap-creasefrom the molten-solder receptacle L, as when soldering the ends of cans,as before stated. The cans may be capped, or the entire head solderedin, the lat-, ter being the most desirable, as the cans are moreconveniently filled.

The machine having all its mechanism sup ported on the vertical shaft 0,and suspended from the hanger A, dispenses with a table or frame,thereby making all the adjustments readily accessible, simplifying themachine, and occupying less space. y
